Adafruit LPS22HB Pressure Sensor - STEMMA QT / Qwiic
Overview
The Adafruit 4633 is a breakout board featuring the ST LPS22HB barometric pressure sensor, designed for high-precision environmental sensing. This board integrates level shifting and a voltage regulator to support 3V to 5V systems, while providing both I2C and SPI interfaces for flexible MCU integration. Its primary function is to measure atmospheric pressure and temperature to calculate altitude or track weather patterns.
Why Choose This Part
This module features dual STEMMA QT / Qwiic connectors, allowing for solderless plug-and-play integration with common development platforms. It includes onboard logic level shifting to ensure compatibility with both 3.3V and 5V microcontrollers without requiring external components.
Applications
Getting Started
Connect the board to an Arduino or Raspberry Pi via the I2C STEMMA QT connector and install the Adafruit LPS22 library from the library manager. For SPI communication, headers can be soldered to the breadboard-friendly pins to interface with high-speed peripherals.
